What is parallel strand lumber used for?

Parallel-Strand Lumber (PSL) is one of the types of engineered or manufactured wood that was developed in the late 20th century. PSLs are usually used in wood-framed construction for girders to support smaller beams of laminated veneer lumber (LVL), wood trusses, or wood I-beams.

What is LSL in construction?

What is Laminated Strand Lumber? Laminated Strand Lumber (LSL) is a type of engineered wood. Manufacturers press together strips of wood that once would have been considered too weak, small, or misshapen to use. This process transforms the scrap wood into solid joists and studs.

What is the difference between LSL and LVL?

Laminated Veneer Lumber (LVL) Its shear strength is superior to LSL but doesn’t quite match PSL’s ability to withstand bending stress. LVL is more expensive than LSL but is affordable compared to PSL and glulam.

What is an LDL in construction?

Laminated veneer lumber (LVL) is one of the most widely used engineered wood products for constructional applications. It is a composite product manufactured from multiple thin layers of veneer that are aligned with the length of the finished lumber.

What is oriented strand lumber?

Oriented strand board (OSB) is a type of engineered wood similar to particle board, formed by adding adhesives and then compressing layers of wood strands (flakes) in specific orientations. It was invented by Armin Elmendorf in California in 1963.

What is the difference between PSL and level?

PSL beams are generally more expensive than glulam, LSL, or LVL beams. PSL beams can be stained or finished where an aesthetically pleasing exposed application is desired. Laminated Veneer Lumber (LVL) is a commonly available engineered product that is manufactured similarly to PSL.

What is difference between LSL and PSL?

LSL is also ideal for use in rim conditions due to minimal shrinkage, cupping, and high fastener holding strength when used in highly loaded diaphragms or for shear transfer at plywood shear walls. Parallel Strand Lumber (PSL) is manufactured from veneers laid into long, parallel strands and bonded together.

What is SCL lumber?

Structural composite lumber (SCL) is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes.

What is Oriented Strand Board used for?

OSB is extensively used for wall sheathing, floor underlayment, roof cover and I-joist in both commercial and residential building. OSB also is used in furniture, reels, trailer liners and recreational vehicle floors.

What does PSL stand for in wood?

Parallel strand lumber (PSL)

What type of wood is PSL?

Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses.
